How the Test Works

Your urine sample is analyzed using a qualitative immunoassay method. This test detects hCG, a hormone produced by the placenta after fertilization. If hCG is present, the test will show a positive result.

What to Expect Before the Test

You may be asked to collect a urine sample in the morning for the most accurate results. Avoid excessive fluid intake before testing if instructed, as it can dilute the sample.

What the Results Mean

A positive result indicates the presence of hCG, which is typically associated with pregnancy. However, a negative result does not definitively rule out pregnancy, especially in the early stages.

When to Follow Up

If you have a positive result, schedule a follow-up with your healthcare provider to confirm pregnancy and discuss next steps. If the result is negative, consult your doctor about further testing if needed.

Frequently asked questions

This test is primarily used as an initial screening tool to determine pregnancy. It is not a diagnostic test for conditions like ectopic pregnancy or miscarriage, which would require additional medical evaluation.
A positive hCG result strongly suggests pregnancy, but a negative result does not always mean you are not pregnant, particularly in the early weeks. Further testing, such as a blood test or ultrasound, may be needed for confirmation.
What happens if I get a positive result?
A positive result means the test detected hCG in your urine, which is a key indicator of pregnancy. Your healthcare provider will guide you on the next steps, such as scheduling a follow-up appointment or additional tests to confirm and monitor your pregnancy.
Can a negative result mean I’m not pregnant?
While a negative result suggests no detectable hCG, it may not always confirm pregnancy, especially in the early stages. If you suspect you might be pregnant, discuss your results with your healthcare provider and consider further testing if needed.
